Answer:

R = -2

Step-by-step explanation

-9, -3 is the first point.

A slope of 1/7 means that for every one unit that "rises" it will have a "run" of 7 units.

-9 - 7 = -2

-3 - 1 = -2 (r)

with a slope of 1/7, (-9, -3) connects to (-2, -2)

Pls mark me brainliest if right thank you

Step-by-step explanation:

Concept to know:

i=√-1

i²=-1

i³=-i

i^{4}=1

the ratio of length and breadth of a piece of land is 5:3 and its breadth is 48m. find the perimeter and area of the land.
Marizza181 [45]

Answer:

256 m and 3840 m²

Step-by-step explanation:

The 3 part of the ratio represents 48 m , then

48m ÷ 3 = 16 m ← value of 1 part of the ratio, so

5 parts = 5 × 16 m = 80 m

Then breadth = 48 m and length = 80 m

perimeter = 2l + 2b = 2(80) + 2(48) = 160 + 96 = 256 m

area = lb = 80 × 48 = 3840 m²
